There are four files for each year, with the following names. 
	- “Charges_” lists the charges filed in relation to each accident. 
	- The “Person_” file list data that is specific to each person involved in the accident. 
	- The “Crash_” file contains information about the accident as a whole. 
	- The “Unit_” file contains information about each vehicle or similar unit in the accident. 

All files contain a variable “Crash_ID” (or similar name) that can be used to match data about each accident from each of the 4 files. 

Information on what the values of each variable means is included in the lookup files. The lookup for 2010 forward is included as it is marginally better organized and the definitions and variables included change very little over the period.

Data from 2010 forward can be found on the website of the Texas Department of Transportation.
